Title: Improvements in or relating to electrical sound reproducing apparatus
IPC: H03G7/02
Filed: 1930-02-12
Abstract: 349,019. Reproducing music &c. KONEMANN, H., 4, Gereonstrasse, Munster, Westphalia, Germany. Feb. 12, 1930, No. 4805. Convention date, Feb. 28, 1929. [Class 40 (iv).] In an amplifier for use in phonograph reproduction from an optical or cut record, a portion of the energy is tapped off at a point in the series of amplifiers, this portion being amplified, rectified, and then supplied as grid bias to one of the main amplifiers, with the result that during silent periods the grid bias is such that the valve working-point is on a flat part of its curve. As shown, a photoelectric pick-up Z is connected through a resistancecoupled chain of valves R1, R2, R3 to a speaker L. Between the valves R1, R2 energy is tapped off and applied to amplifiers R4, R5 and thence through a transformer T to a rectifier G. The rectified current smoothed by the filter K flows through a resistance W2, and during normal reproduction so affects the grid bias of the valve R2 that the valve works on the slope of its curve. When the record is silent, however, the grid of the valve R2 becomes more negative and its working- point is brought down to the horizontal non- amplifying portion of its curve. More than one valve may have its grid bias regulated in this way.

Filed: 1941-04-15
Abstract: 548,632. Coated fabrics., TAYLOR, W. I., WAINWRIGHT, J. A., and FULTON, S. M. April 15, 1941, No. 4901. [Class 140] Transparent or translucent sheet material is made by wetting a woven, knitted or netted open-work fabric with a volatile mobile liquid, then applying a lacquer base dissolved in a volatile liquid identical with or miscible with' the wetting liquid and removing the volatile liquid, e.g. by heat. The fabric may be of cotton, silk, yarn, wire, regenerated cellulose or cellulose derivative. The prepared fabric is one comprising cellulose acetate filaments which have been tightly stretched, e.g. in steam or hot water and then saponified. The fabric may be sized with starch before the treatment. Suitable lacquer bases are cellulose derivatives, polyvinyl and polyacrylic resin and phenol-formaldehyde resin which may be produced by completing in the fabric the condensation of a partial condensation product. The water moisture of the lacquer base may be improved by applying a supplementary coating or, in the use of acetonesoluble cellulose acetate, by esterifying to form a mixed ester as described in Specifications 523,774, [Group IV], 532,673 and 532,674. The dope may contain in addition to solvents, non- solvents, plasticizers, dyestuffs and pigments.

Title: Improvements in circular knitting machines for the manufacture of stockings and the like
IPC: D04B35/00
Filed: 1959-02-13
Abstract: 867,132. Knitting-machines. BILLI, G. Feb. 13, 1959 [Feb. 14, 1958], No. 5014/59. Class 74 (2). As a yarn guide is raised to the inoperative position, its yarn is severed (as by an electrically heated wire 11, Fig. 3, an arc, or a mechanical cutter, Fig. 9), is sucked into a duct 8 and is there held out of the path of the needles until restoration of the yarn guide to its operative position brings the yarn into the path of the needles, which thereupon draw the free end of yarn out of the duct. The mouth of the duct is flattened and extends from the feed point to the knock-over region. The yarn from a guide being withdrawn passes under a tongue 12 on the duct and is thereby positively positioned for correct cutting and holding. When a yarn guide is re-introduced the yarn slips through the needles until the leading needle to take it is about to move out of the knitting sector; and the residual projecting end 10d of yarn is of such size as can be tolerated in the finished fabric. The mechanical cutter comprises a fixed blade 15 and a movable blade 16 raised by a cam 21 and lowered by a spring 22. A two-feed machine may have a relatively long-mouthed duct 24, with an interruption 27 in the length of the mouth and cutting resistances 28, 29 associated with the two sets 25, 26 of yarn guides. Alternatively, there may be provided two independent ducts which eventually enter a common conduit.
